How did you manage to only take 30 minutes, @elliotellis? Tbh if I tried that, I'd probably bolt the wheel on upside down or something.

Wait, two days in a crate fixes it for good? That seems like a lucky break. My aunt's hen went right back to brooding after a WEEK in a separate pen. She was just more angry about it. Chickens get a single idea in their heads and sometimes nothing shakes it. I wouldn't bank on the crate being some magic cure for the next stubborn bird.
